FASTENER.

Application filed January *7, 1927.

My invention ams to provide improvements in fasteners of the turn buttontype.

In the drawings, which illustrate a preferred embodiment of theinvention:

Figure 1 is a front elevation of the complete fastener assembly;

Fg. 2 is a section taken on the line 2-2 of Fig. l, and being partly `inelevation;

Fig. 3 is a section taken on the line 3-3 of Fig. 2;

F ig. 4 is a side elevation of the button or head before being attachedto the body of the stud; and

Fig. 5 is a plan view of the body portion of the stud before the buttonor head is attached.

Referring to the embodiment of my invention as illustrated in thedrawings, I have shown a turn button fastener which comprises a socket Acarried by a curtain 1, or other flexble material, and a turn buttonstud B secured to a rigid support 2, which may be the body of a Vehicleor the like.

The socket is substantially the same as shown and more fully describedin my copending application berial No. 159,688 filed herewth.

The stud includes the pressed metal rigid body portion 3, secured to thesupport 2 by a screw 4, and a resilient button or head 5 also pressedfrom sheet metal. Both the head and body portions of the stud are oblongin cross-section, as shown in Fig. 1.

At the outer end of the body portion, I have provided cam surfaces inthe form of high spots 6 and low spots 7 (Fig. 5), which cooperate withthe button or head 5 in the manner more fully hereinafter descrbed. Anaperture 8 surrounded by a curved Wall 9 (preferably Circular) is alsoprovided in the outer end of the body portion 3.

The button or head 5 is provided with integral fingers 10, which passthrough the aperture 8 and resiliently engage the wall 9 so as to holdthe head in position upon the body portion, as shown in Figs. 2 and 3.Thesefigures are yieldable with the button or head so that, when thebutton or head is turned, it may move aXially to ride up over Serial No.159,689.

the high cam spots 6 and then snap back into the low spots 7. Thisarrangement reduces the number of parts to a minimum, withoutsacrificing any of the advantages of a turn button fastener having moreparts.

When the grommet or socket A is placed over the body 3 of the stud B,the button or head 5 may be readily turned to the position in the lowspots 7, as shown in Figs. 1 and 2, thus eifectively looking the studand socket together. The button or stud is eifectively held in the lowspots 7 by means of the resiliency and shape of the spring fingers lu,as shown in Fig. 2, and cannot rattle or become shifted from apredetermined position by accident.

My invention is not limited'to the particular embodiment shown anddescr'ibed.

Claims.

1. A turn button fastener comprising a body portion, an aXiallyshiftable button or head portion, cam means cooperating between the bodyand head portions to hold the head portion in predetermincd postions,said body portion having an aperture adjacent to its outer end andintegral laterally yieldable means extending from said button or headportion for resilient engagement With a wall surrounding said apertureto secure said portions together and permit axial movement of oneportion relative to the other.

2. A turn button fastener comprising a rigid body portion having anaperture in one end surrounded by a circular wall, a button or headportion having resilient means integral with and extending therefrominto resilient engagement with said Circular wall to secure saidportions together and cam means cooperating between the top of said bodyportion and the bottom of said head portion for holding said buttonagainst accidental turning movement when turned to a predeterminedrelation to said body portion.

3. A turn button fastener comprising a rigid body portion having anaperture in one end surrounded by a circular wall, a resilient button orhead portion having resilient means integral With and extendingtherefrom 'into resilient engagement with said oirhaving divergingportions which may yield cular Wall to secure said portions together,toward each other and permit axial Shifting 10 cam means oooperatingbetween the top of of said button or head portion to permit it said bodyportion and the bottom of said to be turned relative to said cam means.

head portion for holding said button or head In testimony whereof, Ihave signed my portion against aoeidental turning movement name to thisspeoification.

When turned to a predetermined relation to said body portion and saidresilient means GUSTAV JOHNSON.
